Fun facts the venerable Border Gateway Protocol or BGP is using distant-vector algorithm for global Internet routing calculation based on Bellman-Ford dynamic programming approach due to its scability in updating the routing table [1]. For intranet routing however shortest path algorithm based on Dijkstra approach underlies the OSPF and IS-IS protocols. In the old days distant-vector protocol like Routing Information Protocol protocol or RIP is also used but it's now becoming obsolete and humorously known as Rest In Peace protocol. Distant-vector now is making a comeback for intranet in the form of mobile ad hoc and mesh networks (guerilla networks for routing without infrastructure) with Ad hoc On-Demand Distance Vector Routing protovol or AODV [2]. This setup can be very beneficial for disaster and also for mobile group or platoon communication.
